WINDOW-SCREEN.

SPEGIFICATION forming part of Letters Patent No. 637,083, dated November14, 1899.

Application filed July 26, 1898. Serial No. 686,927. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM W. GAsE, of Aurora,in the county of Kane,andin the State of Illinois, have invented certain new and usefulImprovements in Window-Screens; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which-- Figure l is aperspective view from the outside of a window provided with my screen;Fig. 2, a vertical section of the same, and- Fig. 3 an enlarged detailview in vertical section.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to provide a screen for windows thatbesides being inexpensive Will be adapted to such a position in thewindow-frame that the entire window from top to bottom may be screenedand yet neither the free use of the sash nor of any form of inside andoutside blinds or shutters be impeded and no alteration of thewindowframe be necessary to apply the screen; and to these ends saidinvention consists in the Window-screen having the features ofconstruction substantially as hereinafter specifled.

In the carrying of my invention into practice I place the screen, orrather screens, for I employ two, each being of a height to cover halfthe window fromtop to bottom, outside of the glazed sash, and in thecase of a window provided with outside shutters or blinds at a point farenough within as not to interfere with the latter. In order. to adaptthe screens to the narrow space thus afforded, I make their frames andguides of sheet metal.

I illustrate my invention as applied to a Window having outside blinds,and I secure the guides to the side of the blind-stops A and A, eachguide B of the pair for a screen being formed of a piece of sheet metalbent to a U shape in cross-section. The two pairs of guides are soplaced,of course,that the screens in being slid up and down pass by eachother .freely, andthe inner flanges of the guides of the inner screenand the outer flanges of the guides of the outer screen are of suchlength that ample space exists, respectively, above and below them forthe placing in orremoval of the respective screens from their guides.The outer flanges of one pair of guides aline with the inner flanges ofthe other.

Each screen has a frame composed of two 5 5 The flanges 6o fabric isfastened by angular spurs c and c,

formed on such part at suitable locations, which are thrust through thefabric and then bent down upon the latter. The two parts are securedtogether by fasteners D and D,

formed each of a strip of metal that is bent to form a head and twolegs. The legs of each fastener are passed through alinin g openings inthe two parts O and C until the head abuts against one part and thenspread apart where they protrude and pressed against the other part.

A horizontal guide E, of sheet metal, is provided to receive the upperedge of the upper screen, and on the top bar of the frame of the latteris an eye 0 to be engaged by a hook F on the window-frame for latchingsaid screen up. Said eye, being in position to engage the upper edge ofthe other screen, prevents the ascent of the latter far enough to permitits removal from its guides and the descent of the upper screen farenough for removal from its guides.

A handle is attached to the lower bar of the lower-screen frame forsliding the latter, and

it consists, preferably, of a plate G, hinged or pivoted to said bar, sothat it may be turned fiat against the same and not take up much space.v

Having thus described my invention, what I claim is'- 1. The combinationof a window-frame, two pairs of sheet-metal guides therein, arranged indifferent horizontal planes, but with the inner flanges of the guides ofone pair alinwhich has spurs fastening the fabric toit,sub- :0 ing withthe outer flanges of those of the stantially as and for the purposedescribed. other pair, and a screen in each pair of guides, In testimonythat I claim the foregoing I substantially as and for the purpose dehavehereunto set my hand this 8th day of 5 scribed.
